Note: from 1804 to 1812, what would later become the State of Louisiana was known as the "Territory of Orleans". The contemporary "Louisiana Territory" was to the north, and did not include modern Louisiana.

As of August 2014[update], four former governors were alive, the oldest being Edwin W. Edwards (1972–1980, 1984–1988, 1992–1996, born 1927). The most recent governor, and also the most recently serving governor, to die was David C. Treen (1980–1984), on October 29, 2009.

^Removed from power; when Louisiana was readmitted to the Union, Governor Baker and General Winfield Scott Hancock, who appointed him, were removed from power in the state.

^Impeached but never convicted; however, Warmoth was still removed from office with 35 days remaining in his term. All charges were later expunged.

^ abThe State Returning Board declared John McEnery the winner over William Kellogg in 1872, but a second election board was formed that declared Kellogg the winner. Both men were sworn in to office on the same day by opposing legislatures. After armed skirmishes erupted, PresidentUlysses S. Grant stepped in, declaring Kellogg the winner on September 20, 1873.

^Packard was the Radical Republican candidate for governor in 1876. In a disputed outcome, both Packard and his Democratic opponent, Francis T. Nicholls were inaugurated. Nicholls had led in the balloting by some eight thousand votes, but the Republican-controlled State Returning Board cited fraud and declared Packard the victor. Pinchback, however, refused to support Packard and endorsed Nicholls.

^Francis Nicholls won the 1876 election over Stephen B. Packard, but the Republican-controlled State Returning Board declared Packard the winner. Nicholls took office anyway, and assembled a government that was eventually recognized by the federal government as the proper state government.

^As lieutenant governor, acted as governor for unexpired term, and was later elected in his own right.

^Foster's 1896 reelection was characterized by widespread voting fraud which benefited his candidacy. A temporarilly rejuvenated Republican Party united with the Populists behind the candidacy of John N. Pharr and likely won more than the 43 percent attributed to Pharr in the official returns. Foster quickly maneuvered to adopt the state constitution of 1898, which effectively disenfranchised Blacks and induced several decades of one-party Democratic control via White primaries, the winning of which was tantamount to election. See also Regular Democratic Organization and Solid South.

^Resigned to take an elected seat in the United States Senate; Governor Long was elected to the Senate in 1930, but did not take office until 1932, preferring to remain in office as governor.

^Paul N. Cyr was lieutenant governor under Governor Huey Long, and stated he would take over for governor after Long left for the Senate, but Long demanded Cyr forfeit his office. Alvin Olin King, as president of the state senate, was elevated to lieutenant governor and later governor.

^First Louisiana governor elected to consecutive terms after 1921 constitution was amended in 1966 to allow governors to serve two consecutive terms.

^Ibid.Roemer switched from Democrat to Republican several days before the Republicans held a convention in Lafayette to endorse a candidate. Roemer was unable to cancel the convention or to stop its momentum toward U.S. Representative Clyde C. Holloway, who received the endorsement. Both Holloway and Roemer remained in the race, but neither attracted sufficient votes to place in the runoff election.
